IMPROVEMENT IN MACHINES FOR FORMING 'IMITATION BUTTON-HOLES.V

Specification forming part of Letters Patent No. 168,16 l, dated September 28, 1875; application filed l May 14, 1875.

i To all whom t't may concern y Be 'it known that I, JOHN KENNY, of Dover Road, in the county of Surrey, England, have `invented a new and Improved Button-Hole Machine; and I do -hereby declare that `the f'ollowing is a full, clear, and exact description lof the same, reference `being had to the accompanyingdrawing-forming a part of this specification, in which- Figure l is a Verticalfront elevation of the `machine;` Fig. 2, a vertical side elevation; l Fig. 3, a vertical section 5 Fig. 4.', a detail plan view of ythe cams on thermain shaft; Fig. 5, details ofthe die and bed-plate; Fig. 6, details of the stamping-knife.

This invention relates to certain improvements inbutton -holing and apparatus for the same, which is intended to be especially applicable to boot-making, and generally to all otherv analogous uses. It consists in a means for cutting a strip of leather into sections with slotted ends, applying a cord -across the middle of each section, andv so tightening the cord, and ,compressing the whole between dies, as to form a corded button-holetag,

`which may be afterward worked'in with the cord is passed through the eye-piece D, andV is wound upon the feed cord-wheel E. A knife, B', cuts 0E a section of said cord, which is still held by the springs of the cord-wheel until the two griping-jaws F rise and seize it. As the jaws descend the cord foldsthe section of leather around itself, and draws it against and around the projection of the bedplate G, which is of the shape of the button hole, the slits opening as the leather is carried around, and the tongue of one edge lilling up the opening slits of the other edge to form a The die H then compresses the corded tag thus formed into the shape of a button-hole, the said die'having a depression of the shape of abutton-hole, which corresponds to, in shape, and receives the elevation of the bed-plate. As soon as the dieis retracted the eye of the bed-plate, which is movable, and forms a part of a picker-bar, I,

lifts the tag out and transfers it rto a forked y tilt, J, whichv throws it into any convenient receptacle. The presser-foot is attached to an adjustable bar, Z',Which is operated by an `elbow-lever, K. pivoted to the frame, the horizontal arm of which rests upon a cam, L, on

the main shaft, the said horizontal arm having a binding-screw to regulate the throw of the presser-foot. The said foot is brought back to its former position by a second elbow-lever, M, one arm of which is operated Vby a cam, N, on the main shaft, and the other arm of lwhich is attachedv through a spiral spring to the presser-foot bar. rlhe knife C `s attached to a vertical sliding bar, O, contained in a frame, P, and habitually held up by the spring Q. A lever, R, rests upon the top of bar O, and operates-the knife when -drawn down by vertical rod S. Said rod is attached below to a lever, T, which is operated by the cam U upon the main shaft. The

4feed cord-wheel E is journaled in frame P upon the same shaft with a ratchet-wheel, V, and is provided with radial extensions and double clamping-springs a, which hold the cord. The said feed-wheel and ratchet-wheel are intermittently rotated by a spring-seated n springs a a, so that the cut section of cord is still held by the wheel. The rear extension of this knife is loosely attached to a vertically-sliding shaft, C', which is held up by a spring, and depressed by a lever, D', which engages with the cam N, that retracts theV presser-foot. The gripingjaws F are con structed with double pivots, so that they open when compressed, and close when retracted. Said jaws are pivoted to a vertically-sliding shaft, E', which is reciprocated by the forked end of an elbow-lever, F', the other arm of which moves in a cam-groove in disk G' Aof the main shaft to impart said reciprocating motion. The said jaws are attached to the horizontal arms H', which move between the spring guide-bars I' to steady the said jaws, and give them a horizontal adjustment through the cranks J' and segments K'. .The die H is attached to a horizontal slidin g shaft, L', and has a keyhole-shaped depression corresponding to the elevation upon the bed-plate. The said die and plate may be made detachable, and different sizes substituted. The shaft L' is held away from the bed-plate by a spiral' spring, M', and is pressed forward by an elbow-lever, N', the horizontal arm of which is actuated by a cam, O', upon the main shaft, and the vertical arm of which rests against the end of a sliding rod, P', contained within shaft L', which receives the pressure of the elbow-lever, and transmits it to the die through a spiral spring, Q', so as to render the pressure of the die upon the leather elastic. As soon as the tag is pressed into proper shape the picker-bar I, which terminates in a stud, around which is formed the eye of the button-hole, is thrown up by the bar B' and lever S', and the tag lifted out of the die, the lever S' being operated by4 a cam, T', upon the main shaft, to raise the picker-bar, which latter is broughtv back to its former position by a spring, U'. As the tag is lifted by the picker-bar I it is transferred to a forked lift, J, and is tossed by the latter into any convenient receptacle. The said lift is worked by a bar, V', and a lever, W', which is operated by a cam,X,npon the main shaft, the tilt being restored to its position by, a spring, Y'.

Having thus described my invention, what I claim as new is- 1. The combination of presser-foot B, bar

` Z', elbow-lever K, and the cam L'on the main shaft, as and for the purpose set forth.

2. The combination of presser-foot B, elbowlever M, and cam N, substantially as and for the purpose described.

3. The combination of the knife O, bar O, spring Q, lever B, rod S, lever T, and cam U, substantially as and for the purpose described.

4. The combination, with feed cord-wheel E, of the double clamping-springs a a, substantially as and for the purpose described.

5. The combination of cord-wheel E, ratchetwheel V, pawl W, sliding shaft X, lever Z, and disk A', having a cam-groove, substantially as and for the purpose described.

6. The combination of the cord-wheel E, having double springs, the knife B', sliding shaft C', lever D', and cam L, substantially as and for the purpose described.

7. The combination of the griping-jaws F, sliding shaft E','elbowlever F', and disk G', having a cam-groove, substantially as and for the purpose described.

8. The combination of jaws F, horizontal arms H', spring guide-bars I', cranks J', and segments K', substantially as and for the purpose described.

9. The combination of bed-plate G, die H, sliding shaft L', spring M', elbow -lever N', slide B', spring Q', and cam O', substantially as and for the purpose described.

10. The combination of the bed-plate G and the picker-bar I, forming the eye of the button-hole, substantially as described.

l1. The combination of picker-bar I, bar B', lever S', spring U', and cam T', substantially as and for the purpose described.

l2. The combination of the picker-bar I and the forked lift J, for the purpose described.

13. The combination of the lift J, spring Y', bar V', lever W', and cam X', substantially as and for the purpose set forth.

The above specification signed by me this 12th day of March, 1875.
